A conduit outlet box is an essential component in any electrical wiring system. It provides a secure enclosure for wiring connections, junctions, and bends, ensuring safety, durability, and protection against dust, moisture, and mechanical impact.
As a custom conduit outlet boxes manufacturer in China, we specialize in producing a full range of explosion-proof conduit outlet boxes, designed to meet international standards for industrial, commercial, and hazardous area installations. Whether you need conduit outlet boxes for branch conduit runs, 90-degree conduit bends, or straight conduit connections, our factory offers customized designs, high-quality materials, and competitive pricing.
Conduit outlet boxes (also known as conduit bodies or fittings) are used to connect sections of electrical conduit while providing access to the interior for pulling, splicing, and maintenance of wires.
They are commonly used in:
Electrical distribution systems
Industrial control panels
Oil and gas facilities
Marine environments
Commercial building wiring
Depending on the conduit direction and application, several types of outlet boxes are available.
Type | Shape / Direction | Main Use |
Type C Conduit Outlet Box | Straight-through design | For straight conduit connections |
Type LB Conduit Outlet Box | 90° bend with back opening | For 90-degree conduit bends |
Type T Conduit Outlet Box | T-shaped body | For branch conduit runs |
Type LL / LR Conduit Outlet Box | 90° bend (left/right access) | For directional wiring layouts |
Type X Conduit Outlet Box | Cross pattern | For four-way conduit intersections |
Each type is available in different sizes (½” to 4”), materials (aluminum, iron, or stainless steel), and thread standards (NPT, BSP, or metric).
In hazardous or explosive environments such as oil refineries, chemical plants, gas stations, and mines, explosion-proof conduit outlet boxes are essential for preventing ignition of flammable gases or vapors.
Our explosion-proof conduit outlet boxes made in China comply with IECEx, ATEX, and GB3836 standards. Each product is designed and tested to ensure that any internal explosion cannot propagate to the surrounding atmosphere.
Flameproof enclosure structure (Ex d IIB / IIC)
High mechanical strength cast aluminum or iron body
Corrosion-resistant epoxy powder coating
Explosion-proof threaded conduit entries (NPT/BSP)
Weatherproof sealing up to IP66 / IP67
Temperature resistance from -40°C to +80°C
Our explosion-proof conduit outlet boxes from China are widely exported to Southeast Asia, the Middle East, Africa, and Europe, trusted for consistent performance and certification reliability.
Material | Advantages | Applications |
Aluminum Alloy | Lightweight, corrosion-resistant | Indoor/outdoor electrical wiring |
Malleable Iron | High impact strength, rigid | Heavy-duty and industrial setups |
Stainless Steel (SS304/316) | Corrosion-proof, long life | Marine and offshore installations |
Die-Cast Aluminum | Smooth finish, good dimensional accuracy | Commercial buildings |
Surface finishes include electrostatic epoxy coating, hot-dip galvanizing, and anodizing, providing long-term protection against oxidation and environmental corrosion.
These boxes, typically T-type, are used where one conduit branches off from a main line.
They allow easy wire pulling and provide ample space for three-directional connections in compact areas.
Benefits:
Simple installation for complex wiring
Reduces the need for multiple fittings
Available in both explosion-proof and standard versions
LB, LL, and LR type boxes are used for routing conduit in right-angle turns.
Their internal cavity provides space for wire bending and maintenance, minimizing stress on the conductors.
Advantages:
Protects cables from damage during sharp turns
Ensures smooth pulling of conductors
Threaded covers for quick inspection and access
Type C conduit outlet boxes are designed for straight-through conduit connections.
They are ideal for long conduit runs where intermediate access points are required.
Features:
Maintains straight wire alignment
Sealed to prevent moisture and dust entry
Suitable for indoor and outdoor installations
As a custom conduit outlet boxes manufacturer, we provide OEM and ODM services for customers worldwide.
Our engineering and design team can customize:
